Abstract: The disclosed invertible structures rely on combinations of translational movements to effect inversion. An exemplary invertible structure includes a track operable to be slidably coupled to a connector element of a longitudinal structure. In an embodiment, the connector element may include at least two connectors at least partially disposed in a slot defined in the track, which may have a plurality of translational axes for translational movements of the connectors of the longitudinal structure that would effect the inversion of the longitudinal structure.

Abstract: An artificial Christmas tree includes a central trunk broken into at least two separate portions including a fixed trunk portion and at least one rotating trunk portion. The fixed trunk extends up from an underlying base. Rotating trunks rotatably attach at midpoints thereof at least indirectly to an upper end of the fixed trunk. Limbs are pivotably attached to the rotating trunks with optional lights coupled thereto. These limbs pivot between a perpendicular orientation extending from the rotating trunks and a collapsed configuration closer to a centerline of the rotating trunks. The rotating trunks can be pivoted from a first collapsed configuration with a first end above a second end to a deployed configuration with the second end above the first end. During pivoting, the limbs attached to the rotating trunk transition between a collapsed to a deployed configuration automatically. A wheeled base and cover further facilitate storage and deployment.
